I don't think there is any comparable word, though a description might be "external digestion". From the form of the word I would have guessed that it meant something like moving in the direction of (a la tropism) chyle, not the movement of chyle.

1"Chylotrophic" is here introduced as a new word describing organisms which characteristically absorb organic food in solution instead of making or ingesting it. All saprobes and many parasites are chylotrophic.

Yeah, I have been busy (and changed jobs, I am in a completely different field now!)and the forum seems to have been pretty calm as well!

How are you?

If you don't know it, then ask it! Better to ask and look foolish to some than not ask and stay stupid.
